ABSTRACT
Biodiesel was prepared from the non-edible oil extracted from the seeds of Sesbania bispinosa via transesterification. Different factors were studied to find the maximum yield of the biodiesel. It was found that 1:6 oil to methanol molar ratio, 1 %wt of catalyst concentration and 1h of heating at 60 ºC with constant stirring produced maximum yield of biodiesel as 86%. Prepared biodiesel was characterized for different physico-chemical properties examining flash point (177 ºC), density (0.870 g/cm3), kinematic viscosity (4.76 cSt), conradson carbon residue (0.0170 %wt), ash content (nill), distillation range (200-329ºC) sulphur content (0.014 %wt), calorific value (17256.60 btu/lb) and acid number (0.20 mg KOH/g). All the values were within the limits set by ASTMD 6751 standards.
